Pennsylvania gym shooter described as quiet, studious

A man who shot three women dead in a Pennsylvania gym was studious and quiet, according to a woman in a self-help seminar he attended. George Sodini, 48, posted at least two videos on YouTube last year, apparently referring to a desire for a girlfriend in both. Videos of Sodini at a Los Angeles, California, workshop surfaced on the video-sharing site Thursday, two days after he opened fire at a LA Fitness center outside Pittsburgh.
